`new and useful Im rovements in Brake-v Heads; and I do here y declarethat the following is a full, clear, and exact description of the same.

The invention relates to improvements in brake heads, as described inthe present specification and illustrated in the accompan ing drawingsthat form part of the same.

T e invention consists essentially in the novel arrangement andconstruction of parts whereby the han er is locked in the brake headindependent y of the shoe fastening.

The ob]ects of the invention are to avoid the danger incident to thedropping of the brake beam and head due to the accidental. `removal ofthe hanger iroin engagement with said head and to provide a simple,cheap and secure locking device.

In the drawings, Figure 1 is a perspective view of the device showingthe shoe partially in section. Fig. 2 is an enlarged vertical sectionalview showing the fastening. Fig. 3 is a horizontal Afiction of Fig. 2through the hanger recess.

Like numerals of reference indicate corres onding parts in each iigureefei'ring to the drawings, 1 is the brake head here shown as ofsubstantially shell forni having the sides 2 forming the T- shaped slot3 and the inwardly cxtendino lugs 4 and 5, said lugs having theeentra inholes 6 therethrough and the lug 4 having the pin holes 7' therethroughbetween phe central pin hole andthe ends of' said g8 is a recess in thesides 2 and the ieee 9 extending across the brake head. 'l ie said brakehead is formed at the top end iinniediately above said recess 8,with thelongitudinal recess l() for the niain pin and the holes 11 to each sideof said longitudinal recess adjacent to the walls thereof through theuppermost wall of thev recess 8, said holes 11 being in alinement withthe holes 7 12 is the shoe havin the lug 13 depending from the innerside t creof into the space between the lu s 4 and 5, said lug 13 havingvthe central ho e 14 in alineinent with the central holes 6.

15gis the pin extending downwardly through the longitudinal recess 10inthe head throu h the central holes 6 and the hole/14 in t `e lug 13.

16 is the hanger here shown ns of U4 shaped form and inserted in therecess 8 and supporting the brake head 1.

17 is a pin inserted in a hole 11 and-'extending downwardly into a hole7, said pin havn ing the head 18 and the turned over end 19 65projecting beyond the lower side of the lug 4, thus locking thehanger inplace and independently securing the saine of the pin 15.

20. is the brake beam inserted in the T- sha ed slot 3 and extendingacross to a similar rake head at the other wheel lof the car.

It will be thus seen that it is uite impos' sible forthe hanger to shakeout om the recess 8 on the removal of the pin 15 and it is av verycommon occurrence for the said pin 15 to be removed, frequently bydishonest persons for the sake ofthe metal in the shoe, and it is toguard against the accidents liable to happen by the drop ingl of thebrake beam and the shoe, that tiiis anger is eiectually locked in 'asshown in the present invention.

The exact construction as described'herein is not essential, for the pinlocking in the hanger may be arranged otherwise, the salient'featurebeing the introduction of a locking member, apart from the shoefastening What l claim as my invention is:

1. A brake head, having a hanger hole laterally arrangedto the rear ofthe shoeV face and an opening from said hole through said' face, ahanger, and removable vmeans for closing said opening securedindependently of having its closed end of suitable size to slide fthrough said opening into said hole, and means for securely closing saidopening apart froin the ordinary fastening of the shoe to the brake headand removable therefrom.

4. .ln a brake head, a body portion having a recess toward the upper endextending latorally therethrough and lugs projecting inwar ly fromtheinner face, ashoe having a lug on the rear side thereof, a pinextending through said head and shoe lugs, a pin extending through theuppermost wall of said l recess and through one of said hea-d lugs andsuitebllyv turned at its lower end, and a, h enger 1 in said recess.

5. In a brake head, e body portion el" suhstantially shell formationhaving lugs proi jecting inwardly from the inner face und een tral holesthrough said lugs and holes to each side of the center hole in theuppermost of said lugs and a. longitudinal 'recess n how sind uppermostlug and holes through the shell to each side of said longitudinalrecess, :i shoe having a lug extending into thespuce hotween the aoresaid lugs in 'the head, and l central hole in alinernent with theaforesaid g holes, .fi pin extending through said longitudinal recessand said cent1-nl holes in said hond sind shot` lngs'nid a. piny having:L-suitable hemd extending through one of said holes to one side of snidlongitudinal recess into one ol' theside holes in said up )ermost lugund turned over nt its lower end, :ind n hunger in said recessv Signed:it the viti' :ind distriet of Montreal, 1
